Part of the PROception range for the professional aerial and system installer, these high quality earth bonding bars have a variety of uses in distribution systems. Safety earth bonding of systems in accordance with BS EN 50083-1 is the principal application, but the bars are also useful as general-purpose termination panels and patch panels for interconnection between system cables. The use of very high-grade type-F back-to-back female couplers in these bars ensures excellent impedance matching and thus very low insertion loss and freedom from problems caused by signal reflections.
The European safety standard for cabled distribution systems, BS EN 50083-1:1994, requires distribution systems to be designed and constructed so that no hazardous voltages can be present on the outer conductors of cables, or on accessible metalwork. This is usually achieved by earthed equipotential bonding, ensuring that all accessible parts of a system remain at substantially the same potential.
Earth bonding has now almost completely replaced the former practice of using isolated outlet plates, improving both safety and EMC and allowing line-power and control voltages to pass through the outlets.
Other applications
These bars are also useful as general purpose inter-connection or patch panels, where system cables need to be joined reliably, but allowing disconnection for test purposes or providing the ability to re-patch connections where required.
